The N-S Line was the 1st MRT Line in SG and started operations in 1987. As in any system, it was probably built based on some planned operating requirements such as line capacity, usage rate, train frequency, etc. Based on these identified requirements, the line specifications were proposed and built. We can safely assume that when these requirements were put up in the 1970s, a 5million population, carrying capacity and train frequency of 1 train per minute were not part of the requirements.
In recent years, due to influx of migrants, I assume that SMRT were pressured into adding more trains and frequencies to NS Line. Could the power rails, overall system, etc cope with these increased demands in the long term. Did they cause premature wear and tear? Did these premature wear cause yesterday's MRT failure? If they did, whose fault are they?
